Robins is not getting shut down. We are not even on the BRAC list. Additionally, the #1 think the DoD looks at when shutting down a base is the economic impact. That alone will keep it open. Dobbins, on the other hand, is in Marietta, close to Atlanta, with a bazillion other industries around it.
If you are used to a big city life and crime is common, Macon may be okay for you to invest in. I do section 8 in WR and they always need housing and ask if I have homes in Macon
I would not invest in Macon expecting to attract Mercer students. I was a Mercer student. I can tell you that there is no way I would've lived anywhere close to the campus unless I was actually ON campus. It's just not the best area of town. Several guys I know did live in and around college street, but very few girls did. As a parent, I would not let my kid live in that area.
That said, I have contemplated buying a multi-family closer to the law school and medical school, hoping to attract some guys to rent. Not that I wouldn't to girls, its just as a female myself there is no way I would've felt safe walking to campus (either the main campus or the law school). A couple houses came up for sale last year that were right across from the law school campus, literally across the street. Even so, the numbers just did not work. And, keep in mind, most of those houses are quite old and they have the issues that all old houses have, even if they're in great shape.
I'm not sure I'd flip in that area, either, because who's gonna buy? Maybe a professor or something, but most professionals buy in North Macon.
